摘要

为提高永磁同步电机自适应超螺旋控制时的收敛时间和抗扰性能,提出一种基于固定时间干扰观测器的永磁同步电机改进自适应超螺旋控制器。通过在自适应超螺旋控制器中引入幂次项,加快远离原点处控制器的收敛速度,同时将不连续的符号函数替换为连续的h（s）函数,进一步减小抖振。考虑到传统干扰观测器收敛时间长和有限时间干扰观测器收敛时间受初始状态制约的缺点,设计固定时间干扰观测器,使干扰固定时间收敛,干扰估计值送入滑模控制器进行前馈补偿,从而提升控制器抗扰性能。最后通过不同干扰观测器、滑模控制器仿真对比,验证所提控制策略的正确性。

Abstract

In order to improve the convergence time and anti-disturbance performance of the permanent magnet synchronous motor adaptive super-twisting control, an improved adaptive super-twisting controller based on a fixed-time disturbance observer is proposed. By introducing power term in the adaptive super-twisting controller, the convergence speed of the sliding mode controller far away from the origin is accelerated, and the discontinuous symbol function is replaced with a continuous h（s） function, further reducing the vibration. Taking into account the shortcomings of the long convergence time of the traditional disturbance observer and the limited time of the disturbance observer is restricted by the initial state, a fixed-time disturbance observer is designed to make the disturbance converge in a fixed time, and the disturbance estimate value is sent to the sliding mode controller for feed-forward compensation, thereby improving the controller's immunity performance. Finally, the accuracy of the proposed control strategy is verified through simulation comparison between different disturbance observers and sliding mode controllers.
